FIREARM CONTROL.

Specification of Letters Patent.

Patented Jan. 27, 1920.

Application filed April 14, 1917. Serial No. 162,215.

To all whom it may concern Be it known that I, FRANK DAVID ELY, a citizen of the United States, and a resident of Tientsin, China, have invented a new and Improved Firearm Control, of which the following is a full, clear, and exact description.

My invention relates to fire-arm controls, and has reference more particularly to the indicator of the control. The invention constitutes an improvement over my patent issued January 5, 1909 under thenumber of 908,982.

An object of the invention is to provide a direct-reading scale with means for throwing the control into and out of operation by a simple manipulation of the indicator.

Another object of the invention is to provide a control which locks automatically at a predetermined point of the scale.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists-in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a fire arm provided with an embodiment of my invention, part of the fire arm being broken out to show some features of the control and their relation to the indicator;

Fig. 2 is a longitudinal cross section on line 22, Fig. 1;

Fig. 3 is an edge elevation on line '83, Fig. 1;

Fig. 41.- is a face view of the setting block;

Fig. 5 is an elevation of the trigger and the operating mechanism of the fire control seen from the side opposite that shown in Fig. 1. f

Fig. 6 is an enlarged perspective view of the block of the control; and

Fig. 7 is a side view of the pendulum.

Referring to the drawings, 5 is a pendu- Y lum of the control suspended from a pin 4 mounted in the sear and having a transverse tongue 6 at the bottom thereof and a pin 7 depending from the tongue, the pin the slot 25 of the movable block 8 and the tongue adapted to register with the transverse groove 12 of the said block. The block 8 is guided by the groove 9, the

forward end of which curves downwardly for a. purpose hereinafter set forth. The displacement of the block isI controlled by an arm 10 the pivot of which is constrained to move with the indicator arm 11. The firing of the arm is controlled by the register of the tongue 6 of the pendulum with the recess 12 in the block. The above structure is old and is shown in my patent referred to. 4

The indicator arm 11 has a pin '13 at the v free end thereof and is, so mounted on the side face of the fire arm that it may be depressed toward the face. The pin 13 travels in an under-cut of a scale frame 14 secured to the said face of the fire arm. At the upper end of the under-cut for the pin, the frame lat presents a notch 15 for receiving the pin and thereby lock the indicator lever in that position which is marked on the scale frame Off. Itwill be seen that when the indicator arm 11 is brought into that position the block 8, owing to the downwardly curved end of the slot 9,has dropped down away from the pendulum so as not to interfere with its displacement and, therefore, with the firing of the arm, or rifle. This position of the indicating lever throws the control offfrom the arm and permits the use of the arm in any ordinary way.

A screw 16 is revolubly mounted in the frame 14. to move a setting block 17 along the under-cut of the frame. The setting block has an extension 18 projecting or extending into the under-cut provided with an elongated notch '19 for receiving the pin 13 of the indicator arm 11. The yielding properties of the indicator arm tend nor mally to maintain the pin 13 in engagement with the block. To disengage the indicator arm from the block the arm is depressed toward the face of the frame when the pin will be out of the slot and free to move toward the notch 15 for throwing the control into inoperative position. The block 17 has another extension 20 provided with a notch 21 for engaging a spring-actuated plunger 22 mounted in the frame 14. The side edges of the extension 20 are beveled, as shown at 23, to automatically displace the spring-actuated plunger 22 as the block approaches the plunger when displaced by the screw 16 in the frame 14.

WVhen the block is engaged by the plunger it will be locked and its displacementin the fra ne will be prevented. Normally the plunger will be set to lock the block in the intermediate or zero position, but it is self-evident that any other portion of the scale may be selected if so desired. To permit the displacement of the block from its intermediate or locked position, the springactuated plunger 22 must be disengaged from the block and for this purpose a push button '24: is provided. The indicator arm, therefore, may be set to the intermediate or predetermined position without the aid of any scale; in consequence, the indicator arm has two positive positions independent of the scale, one of which throws the control out of action, and the other one which permits the firing of the arm at a predetermined vertical angle. Another angle of action of the control may be obtained by the movement of the block 8'along the groove 9 by which it is guided; and the angularity at which the arm will fire will be indicated by a scale provided along the said guiding groove. It will be noted that the arrangement' permits the use of a direct scale in lieu of an inverted one as was'the case in my patent previously mentioned, it being understood that the block 17 is held in its guideway or groove inthe frame 14 at predete'mnined points or positions for the purposes stated.

The pendulum is suspended to remain vertical, but to prevent the pendulum from acquiring a momentum when the arm is manipulated, the pin 7 is engaged with the slot 25 of the block 8 which limits the swinging are of the pendulum and the latter will come quickly to rest when the arm is aimed. When the tongue 6- of the pendulum registers with the groove 12' of the block, the trigger may be operated and, therefore, the pendulum 5. By adjusting the position of the block 8 by means of the indicator, the position of the fire arm will have to be a tered correspondingly to bring the tongue (3 of the pendulum into register with the recess 12 of the" block to permit the operation of the trigger, sear and pendulum.

While I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.
